BICYCLE-FAN.

SPECIFICATION forming part of Letters Patent No. 681,565, dated August27, 1901.

Application filed February 15,1901. Serial No. 47,498. (No model.)

To all whom t may concern:

Beit known that we, ORLANDO B. MCOUNE and CHARLIE MULL, citizens of theUnited States, residing at lola, in the county of Allen and State ofKansas, have invented a new and useful Bicycle-Fan, of which thefollowing is,

a specification.

This invention relates to fans, and more particularly to fans forattachmentto bicycles, 1o the object of the invention being lto providea cheap, simple, and efficient construction adapted for attachment tothe head of a bicycle and which will be operated from the crank-shaft toproject a stream of -air into the face of the rider, further objects andadvantages of the invention being apparent from the followingdescription.

In the drawings, forming a portion of this specification, and in whichlike numerals of 2o reference indicate similar parts in the severalviews, Figure 1 is a side elevation showing a bicycle with the presentfan attached thereto.

Fig. 2 is a section taken transversely of the apparatus at right anglesto the axis thereof. z5 Fig. 3 is a plan View of the apparatus with theupper half of the casing removed. Fig. 4 is a detail sectional viewshowing the structure of the engaged ends of the casing-sections.

Referring now to the drawings, the present apparatus comprises acylindrical casing, including upper and lower sections 5 and 6, dividedby a plane including the axis of the casing,the edges of the sectionshaving flanges 8 and 9, which-are adapted to abut when the sections areassembled, and to hold the sections together straps 10 and 11 are passedaround the casing and through openings 12 in the flanges above referredto, the sections 4o being also held against displacement longitudinallyby means of flanges 13, formed at the ends of t-he upper section andwhich overlap the upper edges of the ends of the lower section. Thiscasing contains the fan, and to hold it to the head 14 of a bicycle ayokeshaped plate 15 is provided and is disposed with its web portionlongitudinally of and parallel with the side of the casing and with itsends radially of the ends of the casing and 5o projecting slightlybeyond the centers thereof, these arms being held against the ends ofthe lower sections of the casing by rivets or in any other suitablemanner. Brace-plates 17 are also attached to the arms and'ends of thelower section of the casing to more securely hold the arms thereto. Theends of the casing are open at their central portions, and a shaft 18 ispassed longitudinallythrough the casing and projects through theopenings of the ends thereof, the shaft being journaled in bearings inthe arms of the plate 15, and at one end of the shaft and beyond theadjacent arm of plate 15 there is xed a pinion 19 for a purpose thatwill be presently explained.

Upon the shaft 18 and within the casing there is fixed a fan includingblades 20, and which fan is adapted to draw air through the open ends ofthe casing and discharge. it through an opening 21 in the upper sectionof the casing, said upper section having a discharge-spout 22 leadingfrom said opening for properly directing the stream of air. To rotatethe shaft 18 and therewith the fan, a counter-shaft 22 is provided andis j ournaled in the ends of the lower section of the casing andadjacent to the side thereof, and on one end of the shaft is fixed agear 23, which is engaged with the pinion on the fan-shaft 18. The shaft22 has bearings also in the arms of the plate 15 and beyond which itextends, as shown. To rotate the counter-shaft 22 a pulley 24 is fixedthereon and operates in a slot 25 in the side of the lower section ofthe casing, and which pulley has a covering 26, disposed within thecasing and securedv to the wall thereof. A drive-pulley 27 is :fixedupon the crank-shaft 28 of the bicycle, and engaged therewith and withthe pulley 24 is a belt 29. To insure rotation of pulley 27 a loop orstaple 30 is engaged over the adjacent crank 31 of 9o the bicycle and isfastened to the face of the pulley.l

To attach the plate 15 to the head of the bicycle, a loop 32 is passedaround said head and has its ends threaded and engaged through holes inthe web of the plate, beyond which are engaged nuts 33. In the web ofplate 15is a socket 34 to permit it to fit more snugly against thebicycle-head.

With this construction it will be seen that there is provided anextremely cheap and efficient device which may be readily applied andremoved.

In practice modifications of the specific con IOO struction shown may bemade, and any suitable materials and proportions may be used for thevarious parts without departing from the spirit of the invention, and itwill be noted that the blades of the fan are cut away to permit them toescape the covering of the drive-pulley on the counter-shaft.

What is claimed is- 1. A fan attachment for bicycles comprising a casingincluding sections divided in a plane including the axis of the Casin g,straps engaged around the casing to hold the sections from separation, asupporting-bracket connected to one member of the casing, and a fanwithin the casing and having a driveshaft journaled in the bracket, saidcasing having an air-outlet opening.

2. A fan attachment for bicycles comprising a casing, comprisingseparable sections divided longitudinally of the casing, a supportembracing the casing and attached to a section thereof, Ia fan withinthe casing and having a shaft journaled in' the support, flanges forholding the sections against displacement longitudinally, and strapspassed around the casin g to hold the sections against separation.

3. A fan attachment for bicycles comprising a casing having openings inits ends and a discharge-openin g in its side, a yoke-plate disposedwith its arms against the ends of the casing and secured thereto, a fanwithin the casing having a shaft passed through the openings of the endsof the casing and journaled in the arms of the yoke-plate, acounter-shaft passed through thecasing, connections between thecounter-shaft and fan-shaft for operating the latter, said counter-shafthaving bearings in the arms of the yoke-plate, a drive-pulley carried bythe counter-shaft, and means for attaching the yoke-plate to the head ofa bicycle.

4. A fan attachment for bicycles compris- .ing a separable casing havingopenings in its ends and a discharge-opening in its side provided With aspout, a yoke-plate having its arms disposed against and attached to asection of the casin g and projecting transversely of the openings ofthe ends of the casing, a fan-shaft journaled in the arms of theyokeplate and provided with a fan, a gear upon said shaft, acounter-shaft passed longitudinally through the casing and journale'd in`the arms of the yoke-plate, a gear upon the `counter-shaft meshing withthe gear on the ORLANDO B. MCCNE.
